    Default We can NOT send maiils with more than 1MB attachments in webmail

    Hi ALL,


    We Can NOT send mails with 1 Mb or higher attachments to both locally and external domains ( Both in Ajax and HTML modes )

    No issue for sending small atatchments like 64 KB in size.

    We can send emails without attachments. no problem at all.


    Below is my setup ( Multi Server setup )

    My setup is 2 MTAs and 1 mailbox server.

    In MTA1 , primary ldap and nginx are runnig ( 4 GB Ram )
    In MTA2 , Ldap replica and nginx are running ( 4 GB Ram )

    one mailbox server ( 16 GB ram )

    Do I need performence tunning ( like java heap type)

    2 piranha load balancers with a virtuail ip. ( end users connect to this virtual ip )

    We use Zimbra 7.2 64 bit on RHEL 6.2 64 bit

    Dns server (bind) is runnig on all 3 Servers. so 127.0.0.1 is set as in /etc/resolve.conf file in all 3 servers. ( In addition to that, this is a Split domain setup with MS exchange server)

    We incresed attachement size limits too with the following commands on both MTA s.

    su - zimbra
    zmprov mcf zimbraMtaMaxMessageSize 25000000
    zmprov mcf zimbraFileUploadMaxSize 25000000

    What could be the problem?

    We cant NOT send mails with 1Mb or higher attachments from the mailbox server as well as clients PCs. ( all use webmail - port 80 )

    no luck at all

    Hope to hear from you....

    Default

    Hi,

    I would like to give a few more details.

    We configured zimbra Desktop with pop3. Then we can send mails with attachments ( we tried with 1Mb or 5Mb or 8 MB attachments). No problem at all.

    So, I think there's noting wrong with my zimbra multi server setup and routing etc.

    We only Can NOT send attachments with zimbra webmail (i.e port 80 )?

    Your ideas are welcome...
